Area of Science:

  • Cellular Biology
  • Oncology
  • Genetics

Background:

  • Telomeres protect chromosome ends but shorten with each cell division.
  • Telomere shortening is linked to cellular senescence and aging.
  • Uncontrolled cell proliferation in cancer often involves mechanisms to maintain telomere length.

Purpose of the Study:

  • To review the fundamental role of telomere dynamics and telomerase expression in cellular aging.
  • To explore the association between telomere stabilization, cell immortality, and human malignancies.
  • To discuss the potential of telomere biology and telomerase inhibition in cancer diagnosis and treatment.

Main Methods:

  • Literature review of existing data on telomere biology and telomerase.
  • Analysis of the relationship between telomere maintenance and cancer progression.

  • Synthesis of findings to predict future clinical applications.

    • Main Results:

    • Telomere dynamics and telomerase expression are critically involved in cellular aging.
    • Activation of telomerase stabilizes telomeres, promoting cell immortality.
    • This process is strongly associated with the development and progression of human cancers.

    Conclusions:

    • Cell immortalization, often mediated by telomerase, is essential for the growth of most malignant tumors.
    • Advances in understanding telomere biology and developing telomerase inhibitors are expected to significantly improve cancer care.
    • Clinical evaluation of these concepts holds promise for future cancer therapies and diagnostics.
